OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.
METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.
RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).
CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.
